摘要：The study was conducted at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore during the period from July to October, 2007 to find out the effects of rainfall on physiological seed quality of grain amaranthus (Amaranthus hypochondriacus L.) cv. Suvarna. The results revealed that, grain amaranthus crop should be sown from early sowing in Kharif season harvesting higher seed yield with physiological seed quality. Between the crops, Kharif season was better than late sowing as the seeds would be exposed to rain and the rain discolored the seed and reduced its physiological seed quality of grain amaranthus.
